There are following relation in the refractive index of material and its dielectric constant and magnetic permeability:
wherein k is proportionality coefficient; The k value is positive and negative 1; ε is the dielectric constant of material; U is the magnetic permeability of material; Through to the DIELECTRIC CONSTANTS of every bit in the ultra material space and the precise design of magnetic permeability μ; The electromagnetic wave that can realize being sent by antenna 111 is through the sub-lens 121 refraction parallel ejaculations in back that ultra material is processed, thereby guarantees that electromagnetic wave converges and remain with a branch of narrow beam to previous irradiation in long distance, disturbs vicinity electromagnetic communication overlay area thereby further reduce.
Some artificial micro-structurals can realize through the artificial technology; Can design artificial micro-structural by manual work with certain electric magnetic characteristic; Plate shape substrates is divided into a plurality of unit, the base material in each unit with attached to the effective dielectric constant ε of the artificial micro-structural on this unit and the system of selection of equivalent permeability μ be:
Through Computer Simulation and experiment test; The distance of earlier preset emission source and ultra material panel; Unit of preliminary election (comprise in this unit base material and attached to the artificial micro-structural that has certain geometrical shape on the base material) as the unit of center; The electromagnetic electromagnetic property that some unit (the artificial micro-structural that comprises various geometric) response emission source sends is measured; The electromagnetic response curve that measures of storage is confirmed the effective dielectric constant and the equivalent permeability of various different units structures and is present in the database; According to formula S in θ=q Δ n,, confirm the change of refractive amount then, confirm the refractive index at different radii place, from database, select qualified cellular construction according to the relation of refractive index and dielectric constant and magnetic permeability for different deflection angles.
Combine accompanying drawing that embodiments of the invention are described above; But the present invention is not limited to above-mentioned embodiment; The pattern of artificial micro-structural can be two dimension, also can be three-dimensional structure that " worker " font (shown in Fig. 7 A) that is not limited to use among this embodiment can be the derived structure of " worker " font; It can be the alabastrine derived structure shown in each the orthogonal flakes in bar limit in three dimensions shown in Fig. 7 B and Fig. 7 C and Fig. 7 D; Also can be other geometry, wherein different artificial micro-structurals can be that pattern is identical, but its design size is different; Also can be that pattern and design size are all inequality.The quantity that constitutes the substrate of ultra material can increase as required and can subtract, and the structure of each plate base can be identical, also can be different, as long as can parallel ejaculation after the satisfied electromagnetic wave that is sent by antenna 111 is propagated through ultra material panel.
Need to prove, each sub-lens 121 on the electromagnetic wave lens 112 can design the identical refracting characteristic that converges, also can design complete difference and converge refracting characteristic.In this execution mode, electromagnetic wave lens 112 comprise that 12 regular pentagon sub-lens 121 and 20 positive hexagon sub-lens 121 are spliced to form the similar football cavity structure of hollow.In addition; It is understandable that: electromagnetic wave lens 112 can design difformity; Saidly select triangle for use by sub-lens 121; Quadrangle and polygon are perhaps formed the cavity body structure that is spliced into various hollows between them, include but not limited to ball cavity, hemisphere cavity, spherical crown cavity, cylindrical cavity, square cavity etc.
